MSD 8970 Three Stage Retard Control

MSD 8970 Three Stage Retard Control

• Retard timing in three stages
• Set three different timing retards
• Must be used with an MSD 6 or 7 series ignition control
• Retard rate set with plug-in modules
• Supplied with 2/3/4 degree module

The three stage retard control allows you to retard your ignition timing in three different stages. You can activate one retard for a nitrous stage and another at top end in high gear for more mph and still have another module left over for dual stage nitrous systems. When activated together, the retard amounts are cumulative so you get the total of the three. For example, if you pull 2 Degree, then 4 Degree on the second stage and another 2 Degree at top end, the total retard is 8 Degree (2+4+2=8). In addition to the individual retard stages, the three stage retard control has an optional start retard function that retards the timing 10 Degree or 25 Degree while cranking the engine. The three stage retard control connects easily to your MSD Ignition and can be triggered from points, electronic ignitions, crank triggers or magnetic pick-up distributors. It is supplied with a 2 Degree, 3 Degree and 4 Degree module and must be used with an MSD 6, SCI, 7, 8 or 10 series ignition.
